Put this on the "other" forum for you too.
BTW, you got it at an excellent price!
The 1903 model M ( 32acp ) came in 5 variants. Type I, II, III, IV, and V. They varied in barrel length, barrel bushings, magazine disconnects, and finish.
Type I - 1903 -4 inch barrel,
Type II - 1908 - 3 3/4 inch barrel
Type III - 1910 - no barrel bushing
Type IV - 1926 - magazine disconnects
Type V - wartime production - parkerized
Made from 1903 to 1953. Production figures were 572,215.
Yours appears to be an earlier production model based on the rubber grips. It looks to be in good shape except for some bluing wear, so I am guessing NRA Good.
Value would be around $650 with the papers and box. Papers and box alone are worth between $150 - $200, so deduct that if you don't have them.
